Identifier Systems

Most of the (identifier) systems used in NFDI4Health do not have oid yet. Therefore, we

  • assigned ourselves url in the profiles or
  • created Value Sets to be used on identifier.type

    This page summarizes information related to identifiers

Identifiers of Resources

For Resource identifiers, NFDI4Health defines following systems:

System URL or OID Comment
NFDI4Health https://csh.nfdi4health.de/resource/ 1. URL defined ourselves
2. An NFDI4Health identifier is mandatory in each Resource type and assigned by the system.
In Questionnaire, we use the element masterIdentifier to store the NFDI4Health identifier
DRKS https://www.drks.de URL defined ourselves
NCT (ClinicalTrials.gov) https://www.clinicaltrials.gov/ URL defined ourselves
ISRCTN https://www.isrctn.com/ URL defined ourselves
EudraCT https://eudract.ema.europa.eu/results-web/index.xhtml URL defined ourselves
EUDAMED https://ec.europa.eu/tools/eudamed/#/screen/home URL defined ourselves
UTN https://trialsearch.who.int/utn.aspx URL defined ourselves
KonsortSWD https://www.konsortswd.de/ URL defined ourselves
MDM Portal https://www.mdm-portal.de/ URL defined ourselves
Other - 1. We use identifier.type = $UMLS#C0205394 "Other (Qualitative Concept)"
2. User should precise the identifier.system

Additionally we use the value set NFDI4Health_VS_MDS_ID_TYPE_UMLS_Local on identifier.type as we slice the identifier element on identifier.type.

For identifiers of related NFDI4Health resources (uploaded to NFDI4Health' Central Search Hub), we use the Value Set NFDI4Health_VS_MDS_ID_TYPE_UMLS_Local on:

  • relatedArtifact[NFDI4HealthResource].extension:identifier.valueIdentifier.type in ResearchStudy
  • extension:relatedResources.extension:relatedArtifactNFDI4Health.valueRelatedArtifact.extension:identifier.valueIdentifier.type in DocumentReference and Questionnaire

For identifiers of related Non NFDI4Health resources (not uploaded to NFDI4Health' Central Search Hub), we use the Value Set NFDI4Health_VS_MDS_Identifier_Type_Related_Artifact_UMLS_Local on:

  • relatedArtifact[nonNFDI4HealthResource].extension:identifier.valueIdentifier.type in ResearchStudy
  • extension:relatedResources.extension:relatedArtifactNonNFDI4Health.valueRelatedArtifact.extension:identifier.valueIdentifier.type in DocumentReference and Questionnaire

For identifiers related to humans, NFDI4Health uses following systems: ORCID, ROR, GRID and ISNI.

Identifier Abbreviation Full name URL
ORCID Open Researcher and Contributor ID https://orcid.org/
ROR Research Organization Registry https://ror.org/
GRID Global Research Identifier Database https://www.grid.ac/
ISNI International Standard Name Identifier https://isni.org/

As we did not find oids for these systems, we use the Value Set NFDI4Health_VS_MDS_Role_Name_Identifier_Scheme on Practitioner.identifier.type. We do not use Practitioner.identifier.system.

For identifiers related to affiliations, NFDI4Health uses following systems: ROR, GRID and ISNI.

Identifier Abbreviation Full name URL
ROR Research Organization Registry https://ror.org/
GRID Global Research Identifier Database https://www.grid.ac/
ISNI International Standard Name Identifier https://isni.org/

As we did not find oids for these systems, we use the Value Set NFDI4Health_VS_MDS_Role_Affiliation_Identifier_Scheme on Organization.identifier.type. We do not use Organization.identifier.system.
